Nidhi Saini, Rajeev Kumar, Reeta Bhardwaj . LEACH-C Variants using Different Optimization Techniques: A Survey. International Journal of Computer Applications. 178, 4 ( Nov 2017), 46-50. DOI=10.5120/ijca2017915818
Low Energy Efficient Clustering Hierarchy-Centralised (LEACH-C) protocol is one of the most pivotal parts of Wireless Sensor Networks (WSN). LEACH-C protocol employs Simulated Annealing algorithm, which is an optimization technique for cluster-head (CH) selection as well as cluster formation. A number of LEACH-C variants came into consideration that uses different optimization techniques in place of Simulated Annealing for CH selection, cluster formation and data transmission also. This paper provides an insight to such LEACH-C based protocols and also compare their performance in terms of network lifetime, stability period and energy consumption in a tabular form. Network lifetime is compared by evaluating the number of nodes dead with respect to the rounds.
